Question

Somsone建议我使用此功能将我的数据表导出到Excel，但它导出的HTML不仅仅是表格中的数据。如何才能导出数据和格式（宽度，颜色......）？

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script>
function ExportHTMLTableToExcel()
{
   var thisTable = document.getElementById("table").innerHTML;
   window.clipboardData.setData("Text", thisTable);
   var objExcel = new ActiveXObject ("Excel.Application");
   objExcel.visible = true;

   var objWorkbook = objExcel.Workbooks.Add;
   var objWorksheet = objWorkbook.Worksheets(1);
   objWorksheet.Paste;
   alert('test');

}
</script>
  <title>Java Friends</title>
</head>
<body>
  <table id="table" style="font-weight: bold">
    <tr style="background-color:red"><td>a</td><td>b</td></tr>
    <tr><td>1</td><td>2</td></tr>
    <tr>
      <td colspan="2">
        <button onclick="ExportHTMLTableToExcel()">
            Get as Excel spreadsheet
        </button>
      </td>
    </tr>
  </table>    
</body>
</html>

注意：如果安全选项download unsigned activex control和download signed activex control设置为“启用”，则此功能仅适用于IE

请使用此代码，它对我来说很好

public void ExportToSpreadsheet(DataTable table, string name)
        {
            try
            {
                HttpContext context = HttpContext.Current;
                context.Response.Clear();
                context.Response.ClearHeaders();
                String sr = string.Empty;
                sr += "<html><body><table>";
                sr += "<tr style=\"background-color:gray;color:white;\">";
                foreach (DataColumn column in table.Columns)
                {
                    sr += "<th>";
                    sr += column.ColumnName;
                    sr += "</th>";
                }
                sr += "</tr>";
                sr += Environment.NewLine;
                foreach (DataRow row in table.Rows)
                {
                    sr += "<tr>";
                    for (int i = 0; i < table.Columns.Count; i++)
                    {
                        sr += "<td>";
                        sr += row.ItemArray[i];
                        sr += "</td>";
                    }
                    sr += "</tr>";
                    sr += Environment.NewLine;
                }
                sr += "</table></body></html>";               
                context.Response.ContentType = "application/vnd.ms-excel";               
                context.Response.AddHeader("Content-Disposition", "attachment; filename=" + name + ".xls");                        
                context.Response.Write(sr);
                context.Response.Flush();
                context.Response.End();
                context.Response.Close();
            }
            catch (Exception ex)
            {

            }
        }

希望得到这个帮助。

jQuery DataTables TableTools插件可以让您轻松地将HTML表格导出到Excel，但它不会处理格式化。

您可以在此处查看运行插件的示例：http://www.datatables.net/extras/tabletools/

它可能无法处理格式化，但确实可以轻松导出HTML表格。

如果绝对需要格式化，那么您需要考虑将数据发送回服务器，然后让服务器将HTML处理到Excel中。如果您使用的是ASP.net，那么实际上很容易做到。

导出到excel功能不起作用
